SPECIFICATION forming part of Letters Patent No. 736,658, dated August 18, 1903.

Application filed June 16,1902. Serial No. 111,838- (No model.)

To (LZZ whom ii may concern.-

Be it known that 1, GEORGE W. WHITTING- TON, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new an d useful Improvements in \Vire-Fence Machines, of which the following is a specification.

This invention relates to improvements in machines for weaving wire-fencing material having horizontal strands connected by diagonal intermediate wires, the said horizontal and intermediate wires being twisted together at their meeting-poin ts; and the object of the invention is to provide a durable and practi cal machine that will take the wire off of the reels, automatically weave the fence, and reel the finished product into rolls for convenient handling.

I accomplish the objects of the invention by the mechanism illustrated in the accompanying drawings, in which Figure 1 is a top or plan view of my complete invention; Fig. 2, a vertical section on the line 2 2 of Fig. 1; Fig. 3, a right side elevation of the main machine; Fig. 4, an elevation of the opposite or left side of the main body portion of the machine; Fig. 1, a detail in front elevation of the lower right side of the machine, showing the bell-crank to which the twister-levers are attached; Fig. 5, a plan view of the mechanism for securing an intermittent movement of the fencing material through the machine; Fig. 6, a detail in side view of the parts seen from the line 6 of Fig. 5 looking in the direction of the arrow; Fig. 7, a section through the ratchet-wheels shown in Fig. 6 on the line 7 7; Fig. 8, a view of the roller-plate from the line 8 8 of Fig. 5; Fig. 9, a section on the line 9 9 of Fig. 1, showing the wiretwisting mechanism; Fig. 10, an elevation of same looking in the direction of the arrow 10 of Fig 9. Fig. 11 isa detached view, in side elevation, of the twopart shaft and toothed wheel used in the twister. Fig. 12 is a section on the line 12 12 of Fig. 11. Fig. 13 is an end view of the shaft shown in Fig. 11, illustrating the adjustment of the separating distance between the wires. Fig. 11 is a detail in side elevation of the crossbar bearing to receive the wire-twisters with the twistcrs removed; and

' Fig. 15 a top view of the lower bar, showing the seats for the twister-shafts. Fig. 16 is a longitudinal central section of the reel on which the finished product is wound; .Fig. 17, a detail in side elevation and partial section of one of the drum-supports; Fig; 18, a section on the line 18 18 of Fig. 16; Fig. 19, a side elevation and partial section of one of wire-reels. Fig. 20 is a face or edge View of said wheel. Fig. 21 is an end View of a double pair of spool-holders, showing mechanism for rotating the spools and holding and shift ing the fence-wires. Fig. 22 is a similar detail on a larger scale, showing some of the parts broken away and others partially sectioned. Fig. 23 is a longitudinal central section of one of the spool'holders with a spool of elevation of a section of the fence made by my machine. Fig. 25 is adetail on larger scale of the device for holding the wires straight as they leave the twisters.

Like characters of reference indicate like parts throughout the several views of the drawings.

The wires 1, from which the horizontal strands of the fence are formed, are Wound on spools 2 (see Figs. 1 and 2) of any usual and well-known construction. These spools are supported on suitable standards 3.

It will be noted on examination of Fig. 24 that the horizontal strands are closest together at the lower part of the fence,that the middle strands are farther apart than the lower strands, and that the strands of the upper third of the fence are the farthest apart of all. It will also be noted that the horizontal and diagonal wires are twisted together and not simply one wire coiled around the other. The drawings represent a fence having fourteen horizontal strands, and the ma-' chine illustrated is for the manufacture of such a fence.

Arepresents the body of the machine where the fence is formed. Between said body and the spools 2 are the horizontally-mounted spools 4, which furnish the wires 5 for the cross-strands of the fence. The spools at numher one less than the number of horizontal strands. They are placed in a single horizontal row with their axes converging toward the the tension-wheels located adjacent to the wire in operative position, and Fig. 2% is an machine-body A, as shown in Fig. 1. The spools 4 are made to rotate, and both the horizon tal and the cross wires are threaded through therevoluble spool-holders and are held and carried around thereby in unison with the wire-twisters at the machine-body in order to prevent entanglement of said wires by the operative movements of the twisters. Each spool 4 is mounted between circular revolving heads 5 5, and the heads are connected by a half-cylindrical shell 6, which insures uniform rotation of said heads. The disks rest upon friction-wheels 7 7 and have the annular row of cogs 8, whereby the head of one spool is geared to the heads of the spools adjacent to it on either side. The heads are in this manner geared together in two trains or series, one at either end of the spools.

The outside heads are mounted on shafts 8 8, which are connected by bevel-wheels 9 and 10 with the shaft 11 of the body A of the machine. The heads are provided with transverse grooves 12, through which pass the horizontal wires 1. The wires 1 are each carried around two revolutions of a pair of heads and are then transferred to an adjacent pair and carried around twice in the oppositedirection. The wires are held from displacement during the rotation of the heads by plates 13 and 14, (see Figs. 21, 22, and 23) carried by frames 15 and 16, respectively. The plates are pointed, the sides being on curved lines concentric with the axis of the revolving head. The heads have circumferential grooves in which the edges of the plates take, and these edges form guards to retain the wires. One of the frames 15 will have a reciprocating adjustment transmi tted by the rocking bar 17 through arm 18, carried by the bar and pivotally secured to the frame, as shown in Fig. 21. The means for rocking the shaft at right intervals will be hereinafter fully described. Every alternate one of the top row of plates and every alternate one of the bottom row will be fastened to and carried by the frame 15. The remaining plates 14 will be attached to the stationary frame 16. The movable plates will have sharpened ends, which at each shift of the frame are brought between the head and the approaching wire and throw the wire over into the adjacent head, which is rotating in reverse direction. Fig. 22 represents awire being transferred from the right head to the middle one and from the middle one to the one at the left of it. As there are fourteen horizontal wires and thirteen intermediate wires, the machine will require at all times'a pair of heads which is not serving as a spoolcarrier, and as this extra carrier is needed first at one end of the row and then at the other I provide tWo extra pair of heads 19 and 20, located at opposite ends of the row of spoolcarriers, as shown in Fig. 1. The wires 5 from spools 4 pass through suitable openings in the inner heads, as shown by dotted lines in Fig. 23, and are kept from entanglement with the spool by the lug 21.

Located between the reels or spools 2 and the row of spools 4 are the boxes 21, having the shafts 22, on one end of each of which is the grooved tension-wheel 23, around which the wire from the reel opposite it is wound one turn, and to insure a uniform feeding movement of the wheels I connect them together by means of a loose coupling, which permits an arrangement of the shafts on a curve. This coupling consists of a disk 24 with fingers 25 25, which take-into openings 26 26 in the solid web of the wheel 23. The groove of wheel 23 is provided with the transverse ribs 27 to increase the hold on the wire.

The body A of the machine comprises the two sides B and O, which are connected by the cross-bars b, c, and 28 and the several shafts and their attachments.

Mounted transversely of the frame 13 O in suitable boxes is the shaft 28, having pulley 29, to which power is transmitted by belt, as

shown, and mounted near the base of the' termittent movement to the shaft 32 the teeth from f to g on wheel 31 will be removed. Between the space thus bared and the shaft on which the wheel is mounted is the flat raised surface 35, forming a table against which the fiat-sided hub extension 36 from wheel 34 bears and holds the wheel 34 and its shaft stationary while the mutilated portion of the wheel 31 is passing. Mounted upon the cross-bar 28 in suitable ways, as shown in Fig. 15, are fourteen short shafts 36, each having a toothed wheel 37, which meshes with one of the wheels 33 immediately below. Both ends of this shaft are split diametrically, and one of the split sections 38 at each end .is made removable. These sections 38 each have an inwardly-expanding hole 39, which registers with indents or grooves 40 on each side of the mid-shaft and wheel 37. The cross-strand wires 5 are threaded through the openings thus provided. The loose shaft ends 38 are mounted in a sliding reciprocating cap 41, and by sliding the cap the said ends will each be carried from the original position, taking the wire with it and by proper adjustment will be stopped exactly over the next like shaft.' This change of position occurs during the interval of arrested movement of the short shafts brought about by the mutilated wheel 31. The larger and remaining portion of shaft 36 has a longitudinal opening 42, through which one of the horizontalwires 1 is threaded. This opening is enlarged ICC radially of the shaft, shown by the dotted lines in Fig. 123, and the position of the wire in the opening is regulated by the plate 43, which has a perforation the size of the wire and which plate is adjustable in its distance from the axis of the shaft 36. The rotation of shaft 36 causes the two wires which it carries to be twisted together. As a general thing I prefer to make the twist equally in the two wires instead of wrapping the cross-wire around the longitudinal wire; but by setting plate 43 so as to bring the longitudinal wire close to the center of shaft 36 and making a strong tension 011 said wire I can cause the cross-wire to be wrapped around the longitudinal wire without twisting the latter. This is sometimes desirable where extra large longitudinal wires are desired. Each cross-wire is carried back and forth between the same two longitudinal wires by the sliding back and forth of the shaft ends 38. The wheels 37 are held by the stationary bar 4-1, (see Figs. 9 and 14,) over which is the grooved cap e1, which receives the bar 14 in its groove, as shown in Fig. 9. The cap 41 on either side ofbar if is notched on its lower edge to receive the shafts 36. The latter have annular flanges 45, which enter corresponding grooves in the bar 28 and cap l1. These flanges keep the shaft-sections 38 from working longitudinally out of the cap. As the longitudinal wires 1 are different distances apart in three groups, as previously described, I divide the cap in three sections, as shown in Fig. 14, and move each section independently of the others, so as to operatewith their appropriate twistin g-shaf ts. These caps are connected by levers 16 with the arm of a bellcrank 47 (see Fig. 3) at proper distances from the pivotal point of the crank to give the desired movement to the several caps. The lower arm of bell-crank 47 is connected by rod 18 with the crank 49 on the shaft 50. The shaft 50 has the beveled pinion 51, adjacent to which is the wingplate 52.

Mounted in suitable boxes on the frame B O is the shaft 53, on which is mounted the two spur gear-wheels 51 and 55, the teeth of which mesh with those of pinions 56 and 57 on shaft 28. The wheel 5i has a group of teeth 58 on its side, which engage the teeth of pinion 51 at each revolution of the wheel 54. There are just enough teeth 58 to give pinion 51 a half-rotation. \Vheel 5i has atable 59,aga.inst which wing-plate 52 bears to hold its shaft immovable until the teeth 58 are reached. Op-

posite said teeth is a depression (30 in the table,-

which allows the plate to turn over. The crank always stops in a vertical plane and makes a halfrevolution at each movement, thereby imparting a reciprocating movement to the sliding caps. The moments of action and inaction of the several parts are so syn chronized that the twisting-shafts will stop with the removable section s 38uppermost and the joints between them and the body of their that shift the longitudinal wires in the spoolcarriers.

The distance between the points where the cross-wires are twisted with the horizontal wires will be regulated by the rate at which the wires are drawn through the twisters. This drawing of the wires occurs at the interval of rest of the twisters, as above described, and is accomplished by the reeling up of the finished product. This product is carried from the twisters under the drum 68, thence up and over the drum (39 at the top of the frame, and thence down and is wrapped upon the drum 7 O. The drums 68 and 69 are preferably made of circular disks 71, which are connected by a series of closely-placed horizontal rods 7 2. The drun1'70 is removably mounted on shaft-stubs 73 and 7 4, both of which are mounted in suitable boxes supported by the frames B and C. The stub 73 has the sprocketwheel 75 on the inside of the frame, and this wheel has a hub which forms the half of a clutch 7 6. The stub 73 also has the'toe 77, which takes into a socket in the end of the drum-shaft 78. a plurality of disks 7 9, here shown as five in number, from one side of each of which project the pins 80. These pins take into slots 81 in the two parts 89 and 83 of a split disk. The slots are oblique to the radii, whereby by moving the pins in said slots the two parts of the split disk will be separated or drawn closer together. The direction of rotation of the drum in reeling up the fence will tend to force the parts of the split disks apart, and movement in the opposite direction will brin them together. The peripheries of parts 82 and 83 are covered with sheet-metal plates 8 1, forming a two-part drum. The end of the strip of fencing is inserted in the split or opening between the two parts of the drum, and after the amount desired has been reeled upon the drum a reverse movement of the shaft 78 will reduce the drums diameter and permit of the easy removal of the fence-roll. The disks 7 9 have suitable hubs, as shown in Fig. 16, and the hubs of the end disks are turned toward the outside. The hub adjacent to shaft-stub 73 has a half-clutch, forming a part of clutch 76. The shaft 78 extends only part way through the hub at the opposite end of the drum, thereby leaving a socket to receive the end of the stub 74. This stub has longitudinal adjustment controlled by the level-'. 13 y an outward movement of the lever the stub is wit-lulrawn from the hub and the drum re- Mounted on the shaft 78 are TKO leased and made easily removable for the removal therefrom of the roll of fencing. The sprocket-wheel 75 is connected by chain 81 with the wheel 82 on the shaft 53.

'It is obvious that as the drum 70 revolves at a uniform rate of speed, the wires will be drawn more rapidly through the twisters as the diameter of the roll increases on the drum unless some regulation is provided. Such a device I will now describe.

The shaft 84, carrying the drum 69 at the top of the frame, has the notched wheel 85. A lever 86, pivoted to the machine-frame, has a bent upper end which enters one of the notches of wheel 85 and holds it from turning until the lever is disengaged. The lower arm of the lever extends down in the path of a pin 87 on a continuously-revolving disk 88,mounted on the shaft 53. (See Fig. 5.) It has a lug 89, which engages the teeth of a ratchet-wheel 90, loosely mounted on shaft 28. At each revolution of the pin 87 the lever will be moved so as to liberate the wheel 85 and wheel 90. Bythe side of ratchet-wheel 90 is a ratchet-wheel 91, having teeth in reverse order to those of wheel 90. The adjacent faces of these two wheels have opposite depressions 92 and 93. The wheel 91 has a lug 94,which extends into the depression in wheel 90, and the wheel 90 has a lug 95, which extends into the depression in wheel 91. A spring 96 is secured to lug 94 and bears at its other end against the lug 95. The lugs compel the two wheels to move together in a .forward direction, and the spring allows one wheel to move back or in a reverse direction for a limited distance and then brings them back when released, with the spring-pressed lug against the end of the depression. The wheel 91 has an integral pinion 96, which en engages a large spur gear-wheel 97, mounted loosely on shaft 53. Integral with wheel 97 is the sprocket-wheel 82, from which the wheel on the reeling-drum is driven. Mounted in a fixed manner on shaft 28 is the disk 97, having a plurality of lugs 98 (here shown as four) projecting from its side toward the wheel 90. These lugs are preferably provided withrollers and are so shown in the drawings. Pivoted to the adjacent side of wheel is a lever 99, having a head 100, much thicker than the opposite arm 101 of the lever. The lever has a limited movement, controlled by the pin 102, which allows the head of the lever to be thrown out into the path of the lugs 98 of disk 97 and when one of the lugs strikes the head of the lever it and the attached wheel are carried around with the disk 97. This sets in motion the previously-described mechanism, which rotates the drum on which the wire fence is reeled. When the head is thrown back toward the hub of the wheel, the lugs will pass freely over the thin portion of the lever. Normally the lug 89 of lever 86 is in engagement with the teeth of wheel 90, and the wheel 91 is held from moving by the pawl 103. The moment the lever is moved by pin 87, so as to release wheel 90,tl1e spring 96 moves reacts the wheel 91, so as to cause the pin102, which is carried by wheel 91 and passes through slot in arm 101, to move lever 99 into position shown in Fig. 6, with the head 100 in the path of the lugs. The lugs drive the reeling-drum until the upper end of the lever drops into the next lug of wheel 85, whereupon the reel ing operation is stopped and that stops the drawing of the wires through the twisters. The length of wires drawn through the twisters will be controlled by the distance between the notches in the wheel 85. In order to get a firm bearing for the lever 99, I prefer to pro: vide the opening 104 in wheel 90 and allow the additionally-thickened head 100 to extend through the wheel 91, in which pin 10b is seated.

To keep the horizontal wires of the fence in a straight course after they leave the twisters, I provide the wheels 109 and 110, which are mounted in a bearing 107, bolted to a cross bar 108 opposite each twister. The bar 108 is supported by the frames B O. The wheels 109 and 110 are mounted in planes oblique to each other. Their edges are serrated, and the points of the teeth meet each other at the top of the wheels. The adjacent faces of the two wheels have inward extensions, which meet at the top and with the teeth form a triangular inclosure through which the horizontal wires of the fence are passed, as shown in Fig. 25. The toothed construction permits the crosswires to pass without obstruction. The axle 111 is a bent bolt the bend of which is engaged by the center 112 of the support 107.
